Thanks. Nose down info makes sense now. One other question. The height a fast disc needs to get, say 350 feet (10 feet in this post), looks different than the height information given in the articles, where a height of 12 to 20 feet is given. Am I missing something, such as type of disc? I'm throwing a 165 dx orc and sometimes a ce valk and beast, by the way. Considering these and similar discs, what would the heights be for 350 and 400 feet?

One thing to keep in mind is that you probably don't need to be too concerned with disc hieght. If you are getting sufficent hieght to have your discs fade, then that same trajectory will probably be enough for big distance once you start getting the speed neccessary to throw 350-400 feet. Now the disc may start upward, stop at about 8-10 feet and glide then fade. But as you get more speed on the disc it will rise longer, and higher with that same trajectory.
